Abstract
In brief: The saccharin-particle method was used to study nasal mucociliary transport in 11 healthy subjects before and after they jogged 8 to 10 km. The transport time (the time between placement of the saccharin particle on the anterior part of the nasal mucosa and the subject's report of a sweet taste) was significantly longer after jogging (21.7 ± 10.2 min) than before jogging (11.6 ± 6.3 min). The transport times of two control measurements taken an hour apart with the same subjects at rest were similar to one another. Though the findings are clear, the implications of reduced nasal clearance after jogging are speculative and merit further investigation.
